RATIONALE: The shortage of available donor organs limits the development of liver transplantation. This case-serial study presents a novel way to expand the donor pool by using the other-wise discarded partial liver resection graft with hepatic benign tumor. PATIENT CONCERNS: From 2012 to 2016, 15 patients with hepatic lesions were admitted to our hospital. 12 patients suffered from right epigastric discomfort and 3 patients worried about uncertain diagnosis. INTERVENTIONS: Regular hepatic lobectomy was performed for all patients and after back-table management the resected partial liver grafts were used for patients with end-stage liver disease for liver transplantation...

OBJECTIVE: Intracortical brain-machine interfaces (BMIs) are a promising source of prosthesis control signals for individuals with severe motor disabilities. Previous BMI studies have primarily focused on predicting and controlling whole-arm movements; precise control of hand kinematics, however, has not been fully demonstrated. Here, we investigate the continuous decoding of precise finger movements in rhesus macaques. APPROACH: In order to elicit precise and repeatable finger movements, we have developed a novel behavioral task paradigm which requires the subject to acquire virtual fingertip position targets...

There has been a dramatic increase in the emergence of antibiotic resistant bacterial strains, which has made antibiotic choices for infection control increasingly limited and more expensive. In the U.S. alone, antibiotic resistant bacteria cause at least 2 million infections and 23,000 deaths a year resulting in a $55-70 billion per year economic impact. Antibiotics are critical to the success of surgical procedures including orthopaedic prosthetic surgeries, and antibiotic resistance is occurring in nearly all bacteria that infect people, including the most common bacteria that cause orthopaedic infections, such as Staphylococcus aureus (S...

One of the most relevant and open issues within cardiovascular prosthetic hemodynamic performance is a realistic quantification of the damage sustained by red blood cells (RBCs). Specifically, the optimal design of bileaflet mechanical heart valves (BMHVs) requires both low shear stresses along the leaflets and short particle resident times. This study approaches RBC damage estimation by developing a numerical model of RBCs and computing the damage sustained by a set of passive RBCs immersed within in vitro flows...

REVIEW
Dennis Flanagan
Dental implants are placed endosseously, and the bone is the ultimate bearer of the occlusal load. Patients are not uniform in the maximum bite force they can generate. The occlusal biting load in the posterior jaw is usually about three times of that found in the anterior. It is possible for supporting implants to be overloaded by the patients' biting force, resulting in bone loss and failure of the fixture. Bite force measurement may be an important parameter when planning dental implant treatment. Some patients can generate extreme biting loads that may cause a luxation of the fixture and subsequent loss of osseointegration...

PURPOSE: Bacterial biofilms on the surface of prostheses are becoming a rising concern in managing prosthetic joint infections. The inherent resistant features of biofilms render traditional antimicrobial therapy unproductive and revision surgery outcomes uncertain. This situation has prompted the exploration of novel antimicrobial strategies. The synergy of ultrasound microbubbles and vancomycin has been proposed as an efficient alternative for biofilm eradication. The purpose of this study was to evaluate the anti-biofilm effect of stimulated phase-shift acoustic nanodroplets (NDs) combined with vancomycin...

Current neural interface technologies have serious limitations for advanced prosthetic and therapeutic applications due primarily to their lack of specificity in neural communication. An optogenetic approach has the potential to provide single cell/axon resolution in a minimally invasive manner by optical interrogation of light-sensitive reporters and actuators. Given the aim of reading neural activity in the peripheral nervous system, this work has investigated an activity-dependent signaling mechanism in the peripheral nerve...

Titanium and its alloys are widely employed materials for implants in orthopedic or dental surgery due to their mechanical properties, resistance to corrosion and osseointegration capability. However adverse reactions at the tissue/implant interface may occur, which limit the success of the osseointegration process. Therefore, different strategies have to be used to overcome these drawbacks. In this work, we developed two different liposome-based coatings on titanium surfaces as drug or bioactive molecule deposits for dental/orthopedic implant applications...

The ghrelin receptor, also known as the growth hormone secretagogue receptor 1a (GHS-R1a), is a G-protein coupled receptor that is differentially expressed in healthy tissue and several cancers, including prostate, testicular, and ovarian. Selectively targeting the ghrelin receptor using fluorine-18 tagged entities would allow localization and visualization of ghrelin receptor expressing carcinomas using PET imaging. The endogenous ligand ghrelin, a 28 amino acid peptide with 3.1 nM affinity, has poor in vivo stability...

BACKGROUND: Autologous breast reconstruction offers excellent long term outcomes after mastectomy. However, maintaining adequate postoperative analgesia remains challenging. Use of paravertebral blocks (PVBs) reduces postoperative narcotic use and length of stay, and enhanced recovery protocols with mixed analgesia methods are gaining popularity, but few studies have explored the intraoperative effects of these interventions. METHODS: Patients who underwent abdominally based autologous breast reconstruction between 2010 and 2016 were compiled into a retrospective database...

Peri-prosthetic joint infection remains one of the most difficult and challenging complications following hip and knee arthroplasty for both patients and surgeons. Two-stage revision arthroplasty for infection remains the most popular option for the majority of patients and arguably the only option for some. The use antibiotic spacers and in particular articulating spacers has improved the quality of life for patients between stages. The spacers provides local delivery of high concentration antibiotics and provides many benefits to the soft tissues including maintaining soft tissue tension and range of movement...

BACKGROUND: The xenoantigenicity of porcine bioprosthetic valves is implicated as an etiology leading to calcification and subsequent valve failure. Decellularization of porcine valves theoretically could erase the antigenicity of the tissue leading to more durable prosthetic valves, but the effectiveness of decellularization protocols in regard to completely removing antigens has yet to be verified. Our hypothesis was that decellularization would remove the more abundant α-gal antigens but not remove all the non α-gal antigens, which could mount a response...

Late breast implant seroma may be the presentation of a breast implant-associated anaplastic large cell lymphoma (BI-ALCL), which claims for a prompt recognition. However, BI-ALCL diagnosis on fine-needle aspiration (FNA) might be challenging for pathologists lacking experience with peri-implant breast effusions. Sixty-seven late breast implant seromas collected by FNA from 50 patients were evaluated by Papanicolaou smear stain and immunocytochemistry on cell blocks. A diagnostic algorithm based on the cellular composition, cell morphology and percentage of CD30+ cells was developed...

Chondrodysplasia punctata is abnormal calcification in the cartilage of developing bones and has been seen in association with deranged vitamin K metabolism. Warfarin, an oral anticoagulant acting on vitamin K dependent clotting factors is known to cause chondrodysplasia punctata. Despite the knowledge of the condition the management of patients with prosthetic heart valves might require use of the drug for anticoagulation. Here, we present a case of a fetal warfarin syndrome in a second born child of a 27 year lady under warfarin for prosthetic heart valve...
